Every year my kid's school put on Christmas plays, the Nativity in the Infants school and something Christmassy in the Juniors and most kids got to take part. The lead parts always went to the Chair of the PTA's two daughters, a pair of poisonous and spiteful little cows, both of them.
Every year we parents were sent a list of the items we needed to provide for our child's part in the play, and woe betide if the costume wasn't up to snuff. We parents were told off by the PTA chairperson and our kids were belittled by her daughters.
One year we had a new family join the school during the winter term, they had two children a boy of eight and a five year old daughter. Dad was a quiet unassuming sort of chap, mummy was rather strange, sort of Alpha mummy on speed!
It was the best school play I've ever watched!
